I have been wrestling with this issue recently and have also been told by my lab, Buckeye Color, that I should ship them sRGB files. On their website, they state:
"If we were to describe the color space that your monitor can present on screen, it would also be most-closely defined as sRGB. Your Inkjet, dye sub or Pictrography printers and our professional digital printers are.. you guessed it – no greater than sRGB."
So their rational is: Why store color information that you can neither see on your monitor nor print? I don't think we disagree about what a monitor can display but what about their statement that their printers cannot print a color outside the sRGB color space. Is that just their printer? Are there printers that can print colors outside of sRGB? Additionally, Will Crockett on his site Shootsmarter.com
"FACT ONE: there are no printers with a color space (aka output space) that is larger (holding more volume of data) than sRGB. "
Is he just flat out wrong? If so can you provide examples? Assuming you disagree with these statements, what source do you draw your information from?
It seems as though there are a number of people who claim to be experts in this field that are not all saying the same thing and somebody is wrong. I'm just trying to figure out who I believe.
